BACKGROUND

Wireless networking connects one or more wireless devices to othercomputer devices without a direct electrical connection, such as acopper wire or optical cable. Wireless devices communicate data,typically in the form of packets, across a wireless or partiallywireless computer network and open a “data” or “communication” channelon the network such that the device can send and receive data packets.The wireless devices often have wireless device resources, includingfirmware incorporated on original equipment manufacturer (OEM) chipsets,which individually and cooperatively operate and generate data inaccordance to their design and specific protocol or configuration. Suchdesigns and configurations may include, for example, accessing firmwareresident diagnostic tools operable to transmit and receive data in opencommunication connections with networked devices.

Data being transmitted between wireless devices and remote servers oftenincludes sensitive material and may be subject to malicious attack. Forexample, client configurations may be downloaded from a remote server toa wireless device. As these configurations may provide insight into avendor's network operations, a vendor may wish to secure suchtransmissions from prying eyes. Furthermore, network diagnosticapplications resident on a wireless device may transmit networkstatistics or other log information to a remote server. These logs maycontain information useful to a competitor and as a result, may betargeted for interception. Furthermore, intercepting the messagesbetween the wireless client and the server may allow a competitor toreverse engineer the client server interface in order to spoof thelegitimate server and communicate with the wireless client withmalicious intent.

Furthermore, within the wireless device itself, unauthorized clientapplications downloaded to the device may maliciously or unintentionallyaccess an application programming interface (“API”) with handsetfirmware, with the potential for causing damage to the handset and tothe network.

DETAILED DESCRIPTION

Referring to FIG. 1, a secure communications system 100 may comprise, insome aspects, mechanisms and procedures for securely exchangingdata/information between predetermined wireless devices andcorresponding predetermined remote network devices located across awireless network. For example, in some aspects, a first server may beassociated with a first group of wireless devices, and a second servermay be associated with a second group of wireless devices. The describedaspects provide security mechanisms, for example, that preventunauthorized communications between the first server and the secondgroup of devices, and between the second server and the first group ofdevices, thereby providing a secure client/server interface. In furtheraspects, system 100 may comprise mechanisms and procedures for securelyexchanging data/information within a wireless device, such as between aclient application and a wireless device resource. For example, in someaspects, the system provides for security mechanisms that preventunauthorized communications between an application or code resident onthe wireless device and predetermined wireless device resources, therebyproviding a secure client/device resource interface.

For example, in one aspect, an information transfer client (“ITC”)module 122 resident on a wireless device 102 enables securecommunication with an information transfer manager (“ITM”) module 114resident on a remote server 108 over a wireless network 106. As such,system 100 may permit multiple secure and independent networkconnections over a common wireless network. One network may comprise,for example, remote server 108 and at least one wireless device 102associated with one entity, such as a first network carrier. Similarly,a second network may comprise remote server 110 and at least onewireless device 104 associated with another entity, such as a secondnetwork carrier.

Furthermore, in an example of another aspect, a secure resourceinterface module 132 resident on wireless device 102 may be operable torestrict access by client applications, such as ITC module 122, toapplication programming interface (“API”) 112, which provides access todevice resources 128. ITC module 122 may include ITC control logic 124for controlling all operations of ITC module 122 and may communicatewith ITC security module 126. ITC security module 126 provides a secureinterface with remote networking devices, such as remote server 108 andITM module 114, and well as with local device resources, such deviceresources 128 via secure resource interface module 132.

Each of ITC module 122, ITM module 114 and secure resource interfacemodule 132 may include one or more secure mechanisms to provideauthentication, communications setup and secure transfer data. Forexample, such secure mechanisms may include secure hash functions,symmetric key encryption, public key encryption, and any othercryptography mechanism and/or method to ensure the authentication ofparties and the secure exchange of information. Thus, in some aspects,system 100 provides a wireless device with a secure externalcommunications interface and/or, in other aspects, with a secureinternal communication interface.

Referring to FIG. 2, one aspect of a method for securely exchanginginformation within a wireless device may include, at step 140, areceiving a request to access wireless device resources 128. Forexample, a client application, such as ITC module 122, resident onwireless device 102 may interact with device resources 128 to providefunctionality to the device. As such, ITC module 122 may generate arequest to access device resources 128, and such a request may bereceived by secure resource interface module 132. Non-limiting, therequest received at step 140 may be initiated at power up of thewireless device 102, prior to a first request for device data 129, andupon user request. Request 140 may be initiated to unlock API 112 forfuture requests although no resource data 129 need be transmitted atthis time.

This aspect of the method may further include, at step 142authenticating the client application making the access request. Forexample, authentication software may be coded into each API 112, or API112 may call upon secure resource interface module 132 to perform theauthentication. Authentication at step 142 may comprise one or morecryptographic mechanisms, and may include the generation of a digitalsignature by an ITC/resource interface 130 component of the clientapplication. This data may then be forwarded to secure resourceinterface module 132.

Furthermore, each device resource may have different levels of access,and authentication may involve a client application requesting and/orbeing assigned the proper access level. In some embodiments, theassigned access level may be determined based upon a particular securitymechanism, such as a key, provided by the client application at the timeof authentication.

The method may further include, at step 144, exchanging information witha device resource. For example, once authenticated, a client applicationmay make any number of requests of the device resource 128 based on thegranted, predetermined level of access, thereby allowing faster accessto resource data 129. It should be noted, however, that in otheraspects, the number of requests may be limited, and/or each request mayrequire a new authentication.

Additionally, the method may include, at step 146, disabling access tothe device resources. For example, the secure resource interface module132 may, at step 146, remove access to device resource 128 based on alack of activity by the client application. Access may be reestablishedupon re-authentication of the client application. In other embodiments,the interface between a client application and a device resource may bedisabled at power down of the wireless device 102. Furthermore, theinterface between a client application and a device resource may bedisabled by an attempt made by the client application to access devicedata outside of the authenticated access level.

FIG. 3 discloses an aspect of a method by which an application residingon a wireless device and a remote server may, once authenticated, employthe methods and apparatus of system 100 to securely exchange data. Inone aspect, the method may be utilized by an application such as ITclient module 122, which desires to authenticate an IT manager module114 attempting to send commands and/or retrieve information from the ITclient module. For example, such authentication may be desired to wardoff rogue IT manager modules that are not properly associated with thegiven wireless device 102 and/or IT client module 122. In anotheraspect, the method may be utilized by a remote server such as remoteserver 108 to insure that it is receiving information from a properlyassociated wireless device. Referring primarily to FIG. 3, andsecondarily to FIG. 1, at step 152, the method may include establishinga communications connection between a wireless device and a remoteserver. For example, an HTTP connection may be established over wirelessnetwork 106 between wireless device 102 and remote server 108. In oneaspect, the remote server 108 may transmit data to the wireless device102, for example to load a new client configuration or to execute acommand on the wireless device 102. In another aspect, a clientapplication on a wireless device 102 may upload a client log ofinformation collected from the device comprising, for example, wirelessdevice diagnostic data, a spam log, a virus log, network data, etc.

At step 154, the method may include determining if information is to betransmitted or received. For example, if the remote server 108 is totransmit data to the wireless device 102, at step 156, the IT clientmodule 122 may invoke IT client security module 126 to initiate anauthentication process to verify the identity and affiliation of theremote server 108. Methods of authenticating may include remote server108 invoking ITM security module 116 to exchange predeterminedauthentication information, according to predetermined authenticationroutines, with IT client security module 126, and in particular withITC/ITM interface portion 127. For example, the authentication mayinvolve one or more security mechanisms.

As discussed herein, security mechanisms may include, but are notlimited to, digital signatures, secure hash functions, asymmetric keyencryption mechanisms utilizing public and private keys, symmetric keyencryption mechanisms, and session key generation algorithms. Thesesecurity mechanisms may be utilized in one or both of authenticationprocesses and private information exchange processes.

Secure hash functions may provide the basis for electronic signaturesand guaranteeing the integrity of information and operate by taking avariable length message and producing a fixed length hash. Changing asingle bit in the message will change approximately half of the bits inthe hash. The most commonly used cryptographic has functions are MD5(Message Digest), which produces a 128-bit hash, and SHA-1 (Secure HashAlgorithm) that produces a 160-bit hash.

A strong key generation algorithm requires a truly random numbergenerator or at least a cryptographically secure pseudo random numbergenerator. The seeding material for a pseudo random number generatorshould be as long as (or longer than) the session key needed. A pseudorandom number generator algorithm generates always the same output withthe same seeding material; accordingly secure mechanisms 199 may includea seed generator unavailable to others and may be set at the time ofmanufacture, downloading, or implemented in hardware, for example by theuse of a “leaky” diode.

After authentication, the two parties may, at step 158, set up amechanism to transmit encrypted data from the remote server 108 to thewireless device 102. Setup may include the processing of secure setupprocedure 191 (FIG. 6) and may use one or more secure mechanisms 199stored in security mechanism storage 198 to set up encryptedcommunications utilizing symmetric key encryption. Unlike the relativelyslower authentication process of step 156, the speed of symmetric keycryptography may better lend itself to transmitting larger data filessecurely between remote server 108 and wireless device 102. Symmetrickey encryption requires both sender and receiver having the same sharedsecret key. Symmetric key encryption algorithms may be implemented inhardware or software and may include: Data Encryption Standard (“DES”),Triple DES (“3DES”), International Data Key Encryption Algorithm(“IDEA”), Blowfish, CAST-128, and CAST-256.

While these ciphers are fast, key management, that is, the transmissionof the symmetric key over an open wireless channel of wireless network106 is of great concern. Accordingly, asymmetric key encryption,otherwise known as public key encryption, may be employed to solve theproblem of secret key distribution by the use of two mathematicallycomplementary keys. Public key encryption is the foundation ofElectronic Commerce, Digital Signatures and Virtual Private Networking.

Once an encrypted connection is set up, the remote server 108 may, atstep 160, encrypt and transmit data, for example, client configurationinformation and/or commands to the wireless device 102.

As previously disclosed, based upon the methods and apparatus of system100, wireless device 102 is operable to securely transmit a client logor other information to remote server 108.

Referring back to step 154, in the case of transmitting data from awireless device to a remote server, there may be no requiredauthentication of the wireless device 102 on the remote server 108 priorto transmitting the data. In the event of a scheduled data log upload bythe wireless device to the remote server, for example, the wirelessdevice is the device making the call, and as the remote server istheoretically collecting logs from multiple wireless devices,authentication at step 161 is optional. However, some aspects mayinclude authenticating either the wireless device 102 or the server 108,in which case, the authentication at step 161 may include secureprocedures and mechanisms similar to those comprising step 156. In otherembodiments in which authentication is not performed, control may passdirectly to step 162, at which time a secure connection may be set upbetween the remote server 108 and the wireless device 102 using securesetup procedure 191 that may use one or more secure mechanisms 199stored in security mechanism storage 198.

As previously disclosed, symmetric key encryption may be onecryptographic mechanism stored in storage 198 and may be used at step164 to encrypt any data, i.e. log data, generated on wireless device102. Further, after encryption, step 164 may include transmitting theencrypted data, to remote server 108.

Referring to FIG. 4, wireless device 102 may include any type ofcomputerized device such as a cellular telephone, personal digitalassistant, two-way text pager, portable computer, and even a separatecomputer platform that has a wireless communications portal, and whichalso may have a wired connection to a network or the Internet. Thewireless device can be a remote-slave, or other device that does nothave an end-user thereof, but simply communicates data across thewireless network 106, such as remote sensors, diagnostic tools, and datarelays.

Further, wireless device 102 may comprise a computer platform 120 havinginput mechanism 172 and output mechanism 174. Input mechanism 172 mayinclude, but is not limited to, a mechanism such as a key or keyboard, amouse, a touch-screen display, and a voice recognition module. Outputmechanism 174 may include, but is not limited to, a display, an audiospeaker, and a haptic feedback mechanism.

Computer platform 120 may further comprise communications module 188embodied in hardware, software, and combinations thereof, operable toreceive/transmit and otherwise enable communication between componentsinternal to wireless device 102, as well as to enable communicationsbetween wireless device 102 and other devices on network 106.

Computer platform 120 may also include memory 170, which may comprisevolatile and nonvolatile memory such as read-only and/or random-accessmemory (RAM and ROM), EPROM, EEPROM, flash cards, or any memory commonto computer platforms. Further, memory 170 may include one or more flashmemory cells, or may comprise any secondary or tertiary storage device,such as magnetic media, optical media, tape, or soft or hard disk.

Furthermore, memory 170 may be operable to store original equipmentmanufacturer (“OEM”) applications and third party client applications,such as information transfer client (ITC) module 122. In onenon-limiting aspect, ITC module 122 may include diagnostic software, forexample, Remotely Accessible Performance Tool and OptimizeR™ (RAPTOR™)and/or MobileView™ software developed by Qualcomm, Inc., of San Diego,Calif.

Several mechanisms may be used to load applications into memory 170,including but not limited to: static installation at the time ofmanufacture; downloading via wireless transmission over a wirelessnetwork; and over a hardwired connection to a device such as a personalcomputer (PC).

Device resources 128 may include any information, data, code,functionality, etc. resident on wireless device 102. In some aspects,device resources 128 may include all or portions of memory 170. In otheraspects, device resources 128 may include all or any portion ofprocessor assembly 182, which may further include anapplication-specific integrated circuit (“ASIC”), or other chipset,processor, logic circuit, registers, and/or other data processing deviceoperable to execute client applications and application programminginterface (“API”) 112.

Additionally, device resources 128 may include one or a combination ofprocessing subsystems 184 that perform specific operations and/orprovide specific functionality to wireless device 102. In one aspect,such as in a cellular telephone aspect, processing subsystems 184 mayinclude subsystems such as: sound, non-volatile memory, file system,transmit, receive, searcher, layer 1, layer 2, layer 3, secure socketlayer (“SSL”), main control, remote procedure, handset, powermanagement, diagnostics, digital signal processor, vocoder, messaging,call manager, Bluetooth® system, Bluetooth® LPOS, positiondetermination, position engine, user interface, sleep, data services,security, authentication, USIM/SIM, voice services, graphics, USB,multimedia such as MPEG, GPRS, etc. It should be noted, however, thatprocessing subsystems 184 may vary depending on the given device and/orapplication. Further, for example, in some aspects, resource data 129that may be collected by ITC module 122 may reside in registers withinone or more processing subsystems 184.

In one non-limiting aspect, API 112 may be a runtime environmentexecuting on the respective wireless device and may call other modules,i.e., secure resource interface module 132, and device resources 128 asrequired to process requests generated by a client application, i.e.,ITC module 122. One such runtime environment is Binary RuntimeEnvironment for Wireless® (BREW®) software developed by Qualcomm, Inc.,of San Diego, Calif. Other runtime environments may be utilized that,for example, operate to control the execution of applications onwireless computing devices. API 112, as discussed herein, is operable,through secure resource interface module 132, to manage access to deviceresources 128, authenticating client applications prior to issuing adevice call accessing resource data 129.

In some aspects, referring to FIG. 5, API 112 calls upon secure resourceinterface module 132, and its predetermined device data accessprocedures 202, to authenticate a data access request made by the clientapplication ITC module 122. Secure resource interface module 132 maycomprise hardware, software, firmware, data and instructions forcontrolling access to API 112 and its associated device data calls 206that provide interaction with device resources 128. Predetermined devicedata access procedures 202 may include methods and/or routines thatauthenticate components for interacting with device resources 128. Forexample, device data access procedures 202 may require the exchange ofpredetermined messages, authentication and security-related mechanisms,such as device data access security mechanisms 204, etc., in order todetermine whether or not to allow access to at least a portion of API112. Various authentication/security mechanisms, such as symmetric keys,public/private keys, hash functions, digital certificates, etc., may bestored as device data access security mechanisms 204. Device data accessprocedures 202 may vary, for example, depending on an identity of anapplication/component/module requesting access to device resources 128.

Furthermore, in some aspects, secure resource interface module 132 mayprovide varying levels of access to device resources 128. For example,depending upon the specific authentication/security information passedduring the authentication process, API 112 may permit certain devicedata calls 206 to device resources 128 while denying others.Non-limiting, access to device resources 128 may be implemented usingresource/access mapping table 205 that maps a particular access level135 to a particular device resource 128 and requires a specific key 138to unlock the API 112. In operation, secure interface module 132 mayrespond to an application request for a specific access level 135 byusing key 138 to authenticate the client application. If authenticated,a second table, client application/access mapping table 203, may bebuilt to map the authenticated application to the corresponding accesslevel 135. Tables 203 and 205 may both be stored in device data accesssecurity mechanisms 204 and may be used to verify that future data callsto device resources are within the permissible access level of thecalling client application.

Referring back to FIG. 4, ITC module 122 may include hardware, software,firmware, data and/or instructions for gathering device-related and/ornetwork-related information from wireless device 102, and transmittingthis information to a corresponding remote server, such as remote server108. For example, in some aspects, ITC module 122 includes clientcontrol logic 178 operable to execute and control the functionality ofITC module 122. In some aspects, for example, client control logic 178parses ITC configuration 176 and executes information retrieval, storageand transmission functionality based on the given configuration. Forexample, client control logic 178 may require access to device resources128 in order to perform diagnostic on, and/or retrieve information from,wireless device 102 and/or network 106. According to a given ITCconfiguration 176, client logic 178 may, for example, retrieve resourcedata 129 from one or more subsystems 184 and/or may require one or moresubsystems 184 to perform a specific operation. Additionally, forexample, client control logic 178 may create and transmit data log 180,including resource data 129 collected based on ITC configuration 176, toremote server 108. Furthermore, under control of client control logic178, the ITC module 122 may request a download of client configuration176 from the remote server 108 via communications module 188.

Referring to FIGS. 4 and 6, ITC module 122 may include an ITC securitymodule 126 to provide for authentication, and to ensure securecommunications. The ITC security module 126 includes ITC securitycontrol logic 190 operable to control secure procedures for ITC module122. In some aspects, ITC security module 126 may include an informationtransfer client/information transfer manager (“ITC/ITM”) interfaceportion 128 operable to provide authenticated and/or secure exchangeswith ITM 108. In other aspects, ITC security module 126 may include aninformation transfer client/resource (“ITC/Resource”) interface portion130 operable to provide authenticated and/or secure exchanges betweenITC client module 122 and device resources 128, such as via API 112 andthe associated secure resource interface module 132. For example,together with API 112, ITC/Resource interface 130 provides logic forauthenticating client applications on wireless device 102 based upon apredetermined device resource security procedure 196. Similarly, theITC/ITM interface 128 provides logic to authenticate remote server 108,and further comprises secure transmission procedure 192 and securereception procedure 194 to, respectively, transmit and receive encrypteddata between the wireless device 102 and the remote server 108.Procedures 192, 194 and 196 may include predetermined methods, routines,sequences of messages, and secure mechanisms 199 for establishingauthentication and secure communications. For example, secure mechanisms199 may include cryptographic devices and/or algorithms, including, butnot limited to: secure hash functions, such as MD5 and SHA-1; public keyencryption algorithms, such as RSA and pretty good privacy (PGP);symmetric key encryption algorithms, including DES, 3DES, IDEA,Blowfish, CAST-128 and CAST-256; digital certificates; and digitalsignatures.

In addition, in some aspects, ITC security module 126 may include asecurity storage 198 in which one or more of the secure mechanisms 199may reside for access by ITC security control logic 190. For example,security storage 198 may retain public and private keys used byITC/Resource interface 130 and ITC/ITM interface 127, respectively forboth authentication and data encryption/decryption.

FIG. 7 illustrates an information transfer manager (ITM) 108 operable toreceive information, such as data in a data log 180, from residentapplications and subsystems 184 of wireless device 102. In some aspects,ITM 108 may be operable to send software agents or applications andconfigurations, such as ITC module 122, ITC security module 126, SecureResource Interface Module 132, and/or ITC configuration 176, etc. towireless device 102 across wireless network 106 in order to provide forauthentication and security mechanisms and procedures, and to direct thecollection and transmission of information from the wireless device.Furthermore, there may be separate servers or computer devicesassociated with ITM 108 working in concert to provide data in usableformats to parties, and/or provide a separate layer of control in thedata flow. ITM 108 may be a server, personal computer, mini computer,mainframe computer, or any computing device operable to transmit orreceive data to wireless device 102 over wireless network 106.

ITM 108 may include a memory 208 for storing data and instructions, aprocessor 236 for executing instructions and a communications module 238enabling communications internally within ITM 108 and also with externaldevices.

Memory 208 may include an information transfer manager (“ITM”) module114 for managing the collection and analysis of information from one ormore devices, such as wireless device 102. ITM module 114 may include atleast one of any type of hardware, software, firmware, data andexecutable instructions. ITM module 114 may comprise ITM control logic210, which is operable to execute the functionality of ITM module 114.

Some aspects of ITM 108 may require ITM module 114 to generate andtransmit ITC configuration 176 to wireless device in order to collectand report information, such as, device and/or network diagnosticinformation. For example, ITM 108 may be associated with an entity, suchas a network service provider, a device manufacturer, etc., whichdesires to collect device-related and/or network-related informationfrom one or more associated wireless devices, for example, to monitorand/or improve device and/or network performance. ITC configuration 176may comprise, for example, a configuration message that directs a givendevice on what information to collect, on when to collect theinformation, and on when to transmit the information to ITM 108.

ITM control logic 210 is operable to control the operation ofconfiguration generator 212, which may generate ITC configuration 176.For example, configuration generator 212 may allow for a selectionbetween a number of collection and reporting parameters in order todefine ITC configuration 176.

Furthermore, ITM control logic 210 may further be configured to receivedata log 180 from at least one wireless device 102, store the log 180 inlog repository 216, and control log analyzer 220 in the generation ofreport 222. ITM control logic 210 may further operate to control theoperation of control command generator 224 in the generation of controlcommands 226. Control commands 226, when transmitted to wireless device102, are operable to perform such functions as uploading data log 180,downloading ITC configuration 176, as well as any function available onthe wireless device.

Still referring to FIG. 7, ITM module 114 may include ITM securitymodule 116, which includes any hardware, software, firmware, data andinstructions that provide for the authentication of ITM 108 to awireless device, and to allow for the establishment of a securecommunications session between ITM 108 and a wireless device. In someaspects, for example, ITM security module 116 includes one or morepredetermined secure transmission procedure 232 and/or secure receptionprocedures 234, which define predetermined security mechanisms,predetermined authentication processes and predetermined setupprocedures to initiate a secure exchange of information with wirelessdevice 102. For example, predetermined procedures 232 and 234 may beutilized to encrypt/decrypt data transmissions to/from wireless device102. Predetermined procedures 232 and 234 may also include one or moresecure mechanisms 230, such as symmetric, public and private keys, hashfunctions, etc., to encrypt data and/or messages, and/or to provide forauthentication of an identity of a given wireless device and/or of ITM108. In some aspects, for example, ITM security module 116 may include asecurity mechanism storage 228 that serves as a repository for storingone or more security mechanisms 230 in a manner accessible duringexecution of secure transmission and reception procedures 232 and 234.The security mechanisms 230 may be utilized to authenticate ITM 108 to awireless device, and/or to provide a cryptographic mechanism to protectthe privacy of communications between the ITM and the wireless device.

Further, ITM security module 116 may comprise at least one of ITCsecurity module 126 and a secure resource interface module 132. Asdiscussed above, the information transfer client security modulecomprises a first set of predetermined mechanisms and procedures forauthenticating the apparatus to the wireless device and for establishinga secure information exchange, and the secure resource interface modulecomprises a second set of predetermined procedures and mechanisms forauthenticating information transfer client module 122 operable toexecute configuration 176 on the wireless device to the device resource.As such, the secure transmission and reception procedures 232 and 234and secure mechanisms 230 may be correlated to the correspondingprocedures and mechanisms of ITC security module 126 and secure resourceinterface module 132 to protect against improper information retrievalby rogue servers and/or client applications.

Referring to FIG. 1, wireless network 106 may include any communicationsnetwork operable, at least in part, for enabling wireless communicationsbetween wireless device 102 and any other device connected to wirelessnetwork 106. Further, wireless network 106 may include all networkcomponents and all connected devices that form the network. For example,wireless network 106 may include at least one, or any combination, of: acellular telephone network; a terrestrial telephone network; a multicastnetwork such as a Forward Link Only (FLO®) network, including theMediaFLO® System available from Qualcomm, Inc. of San Diego, Calif.; adigital video broadcasting (DVB) network, such as DVB-S for satellite,DVB-C for cable, DVB-T for terrestrial television, DVB-H for terrestrialtelevision for handhelds; a terrestrial telephone network; a satellitetelephone network; an infrared network such as an Infrared DataAssociation (“IrDA”)-based network; a short-range wireless network; aBluetooth® technology network; a ZigBee® protocol network; an ultra wideband (“UWB”) protocol network; a home radio frequency (“HomeRF”)network; a shared wireless access protocol (“SWAP”) network; a widebandnetwork, such as a wireless Ethernet compatibility alliance (“WECA”)network, a wireless fidelity alliance (“Wi-Fi Alliance”) network, and a802.xx network; a public switched telephone network; a publicheterogeneous communications network, such as the Internet; a privatecommunications network; and land mobile radio network.

Suitable examples of telephone networks include at least one, or anycombination, of analog and digital networks/technologies, such as: codedivision multiple access (“CDMA”), wideband code division multipleaccess (“WCDMA”), universal mobile telecommunications system (“UMTS”),advanced mobile phone service (“AMPS”), time division multiple access(“TDMA”), frequency division multiple access (“FDMA”), orthogonalfrequency division multiple access (“OFDMA”), global system for mobilecommunications (“GSM”), single carrier (“1X”) radio transmissiontechnology (“RTT”), evolution data only (“EV-DO”) technology, generalpacket radio service (“GPRS”), enhanced data GSM environment (“EDGE”),high speed downlink data packet access (“HSPDA”), analog and digitalsatellite systems, and any other technologies/protocols that may be usedin at least one of a wireless communications network and a datacommunications network.

FIG. 8 illustrates a non-limiting cellular telephone system 240 andcomprises at least one wireless device 102 and a cellular wirelessnetwork 242 connected to a wired network 244 via a wireless carriernetwork 246. Cellular telephone system 240 is merely exemplary and mayinclude any system whereby remote modules, such as wireless devices 102,communicate packets, including voice and data, over-the-air between andamong each other and/or between and among components of wireless network242, including, without limitation, wireless network carriers and/orservers.

According to system 240, ITM 108 and wireless devices 102 maycommunicate over wired network 244 (e.g. a local area network, LAN) witha public key server 248. Public keys, for example, for use in theauthentication and/or secure communications procedures discussed herein,may be placed on the public key server 248 or sent by E-mail torequesting devices. ITM 108 and public key server 248 may be presentalong with any other network components needed to provide cellulartelecommunication services.

ITM 108, wireless devices 102, and/or public key server 248 maycommunicate with the carrier network 246 through a data link 250, suchas the Internet, a secure LAN, WAN, or other network. Carrier network246 may control the transmission of messages (generally being datapackets) sent to a mobile switching center (“MSC”) 252. Further, carriernetwork 246 may communicate with MSC 252 via a network 254, such as theInternet, and/or POTS (“plain old telephone service”). Typically, innetwork 246, a network or Internet portion transfers data, and the POTSportion transfers voice information.

MSC 252 may be connected to multiple base stations (“BTS”) 256 byanother network 258, such as a data network and/or Internet portion fordata transfer and a POTS portion for voice information. BTS 256ultimately broadcasts messages wirelessly to wireless devices 102, suchas by short messaging service (“SMS”), or other over-the-air methods.

FIG. 9 illustrates an aspect of a method by which a remote server 108may authenticate the identity of a wireless device 102 prior totransmitting data, i.e., client configuration and/or commands, to thewireless device 102. It should be noted that the method of FIG. 9 is oneexample of a plurality of possible authentication methods that may beutilized based on the discussion provided herein, and thus this exampleshould not be construed as being limiting. In some embodiments,authentication mechanisms may be implemented by the ITC module 122stored on the wireless device 102 in operation with the ITM module 114on remote server 108.

At step 262, in some aspects, the method may include establishing aconnection to a remote server. For example, wireless device 102 mayinitiate an HTTP connection between communication modules 188 and 238 ofwireless device 102 and remote server 108, respectively. The connectionmay be made under the control of the client control logic 178 ofwireless device 102 and ITM module 114 of remote server 108, and mayemploy a secure socket layer (“SSL”) to establish a secure connectionbetween a client and a server.

At steps 264 and 266, the method may include generating a random messageto use as a basis for comparison in an authentication procedure, andtransmitting the random message to a remote server. For example, undercontrol of ITC security control logic 190 and secure transmissionprocedure 192, a random message is generated and may be transmitted tothe remote server 108 at step 266.

On the remote server, at step 268, the method may include receiving therandom message and applying a predetermined security mechanism to therandom message to create a server message digest. In this case, thesecurity mechanism may comprise some cryptographic mechanism only knownby both an authenticated wireless device and an authenticating remoteserver. For example, ITM security module 116 may receive the transmittedrandom message and, based upon secure transmission procedure 232, applya predetermined secure hash function to the message at step 268,creating a server message digest. The hash function generator and othercryptographic algorithms coded in security mechanism 230 are stored insecurity mechanism storage 228. The server message digest will be usedat a later step to determine authenticity of the wireless device 102.

At step 278, on the wireless device, the method may further includecreating an application digest based on applying a predeterminedsecurity mechanism to the random message. As noted above, thepredetermined security mechanism used by the wireless device should bethe same security mechanism known to and used by the remote server inorder for the device and server to be properly authenticated. Forexample, after the ITC/ITM interface 128 transmits the random message tothe ITM security module 116, the client application may, at step 278,apply its own predetermined hash function to the random message creatingan application message digest.

At step to 280, the method may include encrypting the application digestto create a cipher digest, for example, to allow for the securetransmission of the application digest across a network. For example,the ITC/ITM interface 128 may encrypt the application digest with apublic key to create a cipher digest. Further, the method may includetransmitting the cipher digest to the remote server. For example, theITC/ITM interface 128 may transmit the cipher digest to remote server108.

At step 276, on remote server, the method may include decrypting thecipher digest to obtain a server/application digest. For example, theITM security module 116 is operable to decrypt the received cipherdigest using a private key, corresponding to the public key used by thewireless device, stored in security mechanism storage 228.

And, at step 270, the method may include comparing the server messagedigest with the server/application digest to determine if they areequal, and hence, to authenticate the wireless device. For example, ITMsecurity module 116 may compare the server/application digest decryptedin step 276 with the message digest created at step 268. If the twodigests are equal, then the wireless device 102 is authenticated, andthe set-up of an exchange of information may proceed with step 272. Ifthe two digests are not equal, then the wireless device is notauthenticated, and the communication may be terminated at step 274.

Modem encryption systems use a combination of symmetric and public keyencryption. In some aspects, as noted above, the methods and apparatusdisclosed herein may take advantage of the speed of symmetric encryptionand the key management advantages of public key encryption to exchangedata quickly and securely between remote server 108 to wireless device102.

FIGS. 10 and 11 illustrate an aspect of a method to generate and encrypta session key on a wireless device 102 and then transmit the encryptedsession key to a remote server 108. It should be noted that the methodof FIGS. 10 and 11 are one example of a plurality of possible securecommunication set-up and exchange methods that may be utilized based onthe discussion provided herein, and thus this example should not beconstrued as being limiting. In some embodiments, wireless device 102may comprise, as part of ITC security module 126 and security storage198, stored secure mechanisms 199 that may include public keys of remotedevices and their complementary private keys.

At step 283, wireless device 102, and more particularly, the securetransmission procedure 192 of ITC/ITM interface 127, is operable toretrieve the public key of the remote server. In some embodiments, theremote server's public keys may comprise secure mechanism 199 staticallyloaded into security storage 198 at the time of manufacture of wirelessdevice 102. In other embodiments, the wireless device 102 may obtain thepublic key directly from the remote server 108 across the wirelessnetwork via communications module 188. In other embodiments, thewireless device may retrieve it from a third party, as illustrated bykey server 248 in FIG. 8. In further embodiments, keys may be enteredvia input mechanism 172 such as from a PC, keyboard, and other inputdevices previously disclosed.

Following step 283, the secure transmission procedure 192 may, at step284, generate and store a random session key. The session key may begenerated by one of secure mechanisms 199, and may include a softwareimplemented version of a pseudo random number generator. In someaspects, the session key may comprise a symmetric key, which providesfor a high rate of data exchange, relative to an asymmetric key pair,while still protecting the privacy of the exchanged data.

At step 285, the session key may be encrypted with the public keyretrieved at step 285, and transmitted to the ITM security module 116 ofthe remote server 108 at step 286.

Since the ITM security module 116 has the private key of thecomplementary key pair, only the remote server 108 can recover and storethe session key at step 287.

FIG. 11 is a continuation of FIG. 10 and illustrates an aspect of amethod by which remote server 108 may forward encrypted datatransmissions to wireless device 102. After decrypting and storing thesession key at step 287, the ITM security module 116 may, at step 290,encrypt and, at step 292, transmit any data required to be forwardedsecurely to wireless device 102. This data may include clientconfiguration 170, control command 226, and any other server based data.

At step 294, the wireless device 102 may use the session key stored atstep 284 in security storage 198 to decrypt the encrypted informationtransmitted by remote server 108. In one aspect, the decryption may beimplemented by the ITC/ITM interface 127, and more specifically, securereception procedure 194 of interface 127. Upon completion of step 294,wireless device 102, under control of client control logic 178, mayparse the decrypted data at step 295. In one aspect, the data comprisescommands to be executed on the wireless device. In other aspects, thedata comprises configuration data which is stored as ITC configuration176.

Optionally, at step 296, once the information from remote server 108 isdecrypted and parsed, wireless device 102 may delete the session key. Anew information exchange may then require a new session key, therebyproviding for enhanced security in exchanging information.

In some embodiments, the wireless device may transmit a statusindication back to the remote server. In other embodiments, the wirelessdevice may, at step 298, simply disconnect from the remote server 108 ifno further communication is required.

FIG. 12 illustrates one aspect of the secure architecture in which datalog 180, or any other wireless device data, is securely provided to theremote server 108. It should be noted that the method of FIG. 12 is oneexample of a plurality of possible secure transmission methods that maybe utilized based on the discussion provided herein, and thus thisexample should not be construed as being limiting.

At step 302, the wireless device 102 may initiate a connection, an HPPTconnection, for example, with the remote server 108. This connection maybe used to retrieve the remote server's public key at step 304. Aspreviously disclosed, the public key may be obtained via variousmechanisms including downloading it from the remote server, via a thirdparty, and being statically loaded onto the wireless device at the timeof manufacture or via a PC.

At step 306, the wireless device 102 may generate a random session key,which at step 308, may be used to encrypt data log 180.

At step 310, the session key may be encrypted with the remote server'spublic key and at step 312 both the encrypted data log and the encryptedsession key may be transmitted to the remote server 108 over thewireless network 106.

Since only the ITM security module 116 has the private key of the keypair, only the remote server 108 may operate, at step 316, to recoverthe session key and at step 318, decrypt the received encrypted data log180. At step 320 the remote server 108 may transmit an acknowledgementoperable to notify the wireless device 102 of the successful transfer ofdata. After receiving the acknowledgement at step 322, the wirelessdevice may, at step 324, disconnect from the remote server.

As previously disclosed, the secure architecture described hereinincludes an authentication mechanism protecting static extension API 112from access by a non-authenticated client application. FIG. 13 disclosesone such authenticating mechanism and includes a secure resourceinterface module 132 being called upon by API 112 to authenticate clientapplication ITC module 122. Intra-wireless device communications betweenthe secure resource interface module 132 and ITC module 122 may beperformed by communications module 188 under control of API 112.

As previously disclosed, authentication may be performed once, atstartup, initialization/downloading of the client application, at ascheduled time, and at a time determined by the user. Onceauthenticated, API 112 may process client application requests untilsuch time as the API/client application interface is disabled. Theinterface may be disabled via several mechanisms including: timing out,lack of activity for a determined amount of time, and power down of thewireless device.

Furthermore, authentication may involve assigning a specific accesslevel to an application, based upon information transferred between theclient application and the API at the time of authentication. Accesslevels may amount to permissions, wherein the wireless device may grantone application more or less permissions to access wireless deviceresources. Access to device resources 128 may be controlled using apredetermined resource/access level mapping table 205 and a clientapplication/access level mapping table 203 generated at the time ofclient application authentication.

Referring to FIG. 13, a method for authenticating a client applicationis illustrated. It should be noted that the method of FIG. 13 is oneexample of a plurality of possible client application authenticationmethods that may be utilized based on the discussion provided herein,and thus this example should not be construed as being limiting. Themethod may start at step 330 with ITC module 122 generating a message,which at step 332, may be transmitted to secure resource interfacemodule 132 where it is received at step 334. The generated message maybe random, or may comprise information regarding an access level 135,indicating the level of access required by the client application.

The secure resource interface module 132 may, at step 336, apply asecure hash function to the message generating a message digest to beused for authenticating the client application at step 348. The securehash function generator may be included with other cryptographicfunctions stored in device data security mechanism 204.

In addition to forwarding the message to secure resource interfacemodule 132, step 330 may include passing control to step 338, at whichtime the ITC security module 126 portion of the ITC module 122 may applyits own secure hash function to the message generated at step 330. Thesecure hash function applied by the ITC module 122 may be implemented incode as part of device resource security procedure 196.

At step 340 the ITC security module 126 may encrypt the message digestof step, and at step 342, transmit the cipher digest to secure resourceinterface module 132.

The cipher digest may, at step 344, be received by the secure resourceinterface module 132 and, at step 346, decrypted using a mathematicallycomplementary key to the key used in step 340.

At step 348 the message digest generated in step 336 is compared to themessage digest decrypted from the cipher digest in step 346. If the twodigests are equal, the authenticity of the client application and theaccess level contained in the body of the message received in step 334may be determined at step 351. Once determined, a client applicationaccess level 135 may be stored in client application/access mappingtable 203 along with client application identification (ID) 137identifying the specific client application. The client ID 133 and theassociated access level 135 may be checked by the API 112 in subsequentclient application data calls 352 to determine whether to grant accessto device resource data 129. In other embodiments, no additional checksof the client application data calls 252 may be made and onceauthenticated, all subsequent data calls are processed without furtherchecking,

If the digests compared at step 348 are not equal, API 112 is locked atstep 350 and the client application is blocked from accessing the deviceresources requested.

Thus, in some aspects, a wireless device, and in particular aninformation retrieval client on the wireless device, is provided withmechanisms and routines that assure that a remote device requesting theinformation is properly associated with the wireless device and/or theinformation retrieval client. These mechanisms and routines assure theremote device requesting information is not a rogue device trying tosteal information. Further, in other aspects, wireless device resourcesare provided with mechanisms and routines that assure secured access tothe resources and their associated device-related and/or network-relatedinformation. Such mechanisms and routines assure that only authenticatedand properly affiliated information retrieval clients are allowedaccess, thereby thwarting rogue information retrieval clients.

In some aspects, the affiliation between the wireless device and theremote server allows the properly authenticated remote server to controlthe settings of the authentication and secure information transfermechanisms and protocols. The remote server may change the mechanismsand protocols on the wireless device at any time to provide for enhancedsecurity. Similarly, once dealing with an authenticated remote server,the wireless device may direct changes with the mechanisms and protocolson the remote server. For example, once authentication and secureinformation exchange is established, prior to disconnecting, the remoteserver and/or the wireless device may conclude an information transfersession by establishing new secure mechanisms and/or routines to use forthe next session. Further, in this same manner, the authenticationmechanisms and routines, and the secure exchange mechanisms androutines, between the client application and the device resources may beestablished and changed by the remote server, and/or by the wirelessdevice.
